  1. The Prevalence of Respiratory Diseases according with the level of Tobacco Dependence among an oil company workers Authors: Oana Cristina Arghir¹, Anamaria Bechir², Gheorghita Voicu³ ¹Constanta "Ovidius" University²Bucharest "Titu Maiorescu" Faculty³Constanta Clinical Pneumology Hospital

  2. Settings: • Considering that a given environmental chronical exposure to chemical substances used in oil industry may influence the risk of occupational respiratory pathology, our study proposed to assign the prevalence of respiratory diseases, moslty COPD, concerning on the role of additional smoking exposure in an oil company’s workers from an south-eastern Romanian region.

  3. Tabel 1- General characteristics of randomized persons grouped by direct exposure to chemical air polution General characteristics of randomized persons grouped by direct exposure to chemical air polution

  4. Workers may be at risk for lung disease if the air they breathe at work contains an excessive amount of dust, fumes, smoke, gases, vapors or mists. Workers who smoke are at a much greater risk of lung disease if they are exposed to substances in the workplace that can cause lung disease. Poor ventilation, closed-in working areas and heat increase the risk of disease. Outside air pollution can also increase the risk of lung disease in people who work in jobs that expose them to substances that can cause lung disease. Chemical substances used in oil industry processes Organic solvents: aliphatic and aromatic hydrocarbons, Petroleum solvents, acids, Respirable dust

  5. Purpose: • To collect available data on nicotine dependence, as defined by the Fargerstrőm Test of Nicotine Dependence (FTND); • To compare levels of dependence among exposed workers, assigning the prevalence of smoking and respiratory diseases, especially COPD prevalence.

  6. Material & methods: • Prevalence study conducted from in 2002 consisted in a two part process of symptom-based questionnaire inspired by ECRHS and FTND; • The prevalence study included subjects identified as exposed workers with a perriod of exposure > one year. • Those who reported respiratory symptoms, by using a simplified questionnaire (inspired by ECRHS), • were selected, • performed lung function tests (Flow Screen Jaeger device, • and interogated with more details about smoking, follow-up FTND questioning of active smokers.

  7. Results: • 202 were identified as exposed workers (E) with a mean perriod of exposure of 12.4 yrs +/- 7.253 s.d. (lim: 1-32 yrs.). • 65.35% of workers reported respiratory symptoms (n=132/202), • 84% of randomized workers (n=111/132) had a suggestive symptom- based questionnaire for a respiratory disease; • 60.79% of all workers recognized smoking(n=143/202); • 93 of them recognized tobacco dependence, according to FTND (with 4 different degree of nicotine dependence).

  11. The prevalence of respiratory diseases and disorders among active smokers workers

  12. Impact of smoking on COPDamong oil company workers Prevalence of COPD was greater in active smokers (n= 43/93; 46%) p<0.002 1 Ex-smokers 12/50; 24% 2 Non smokers 8/59; 13.5%; 3 Active smokers 48/93; 51.6%

  13. FTND Score dependenceseverity among smokers +/- COPD

  14. The impact of nicotine dependence on COPD Prevalence [COPD Prevalence: 33.6% in oil Company workers (n= 68/202)]

  15. The impact of nicotine dependence on COPD Prevalence, according with FTND COPD Prevalence has a progressive increase among smokers, according with the degree of nicotine dependence (from low: 38.9% to extreme 91.6%).

  16. Conclusions: • The prevalence of respiratory disease in oil company exposed workers is significantly correlated with smoking addiction. • A simple FTND can be used to identify patients with a high likelyhood of having COPD, for whom strong dependence is particularly important (mostly to eliminate the occupational exposure component).

  17. Clinical Implications: • Most respiratory guidelines agree that spirometry is the basis for COPD diagnosis and Fagerstrőm Test of Nicotine Dependence might enhance the diagnostic accuracy of COPD.
